W. A. OTOOLE ADJUSTABLE WHDGE FOR LOCONOTVE DRIVE' BOXES Filed Ot. '7, 1925 2 Shmat's--ShoetV 2- reached, or until the under side of the head 28 contacts with the rib 15. llfh'en this con-. dition is reached, the terminals 33 of the indicator will be spaced a correspond- `ing .distance away from the shoulders 18.

An inspector `examining the locomotive Vcan readily gauge whether the wedge boltY needs to be further adjusted by noting the distance. between the top of the terminals and the under sides Vof the shoulders 13. lf the distance between the terminals 33 and the shoulders 13 indicates that substantially no further automatic adjustment of the wedge can take place by reason of the expansion of the springvO, the bracket Zal is removed, nut 28 is loosened and the sleeve 1G is rotated to again restore the parts to the position shown in Figure 3. Repeated adjustments can be made until the wedge re,- quires relining, at-which time the bolt 2'? will be extended upwardly to its highest position in its respect to the sleeve 1G.

`When the wedge has been adjusted to its limit, it may be removed for the purpose of relining it, as is the'iisual practice. To remove the wedge for relining, bracket '24 is removed and nutQS is rotated.V The sleeve lf3 may be rotated to the left, causing the sleeve to screw up on the bolt, lifting flange lit the nut 23 is 18 off the pedestal brace. then tightened, sleeve 1G will be drawn down until flange 18 again bears against the pedestal brace. I This serves to pull the wedge down.v making it sufficiently loose to be readily removable when the pedestal brace is dropped down. Y

lf desired, indicator 3l cani be omitted, but its presence enables an inspector to more readily determine when some adjustment of the wedge bolt is necessary.

l claim as my invention:

1. An adjusting screw mechanism for drive box wedges including an intei'iorly threaded sleeve having an extei'iorly threaded end portion, a lock nut on said exteriorly threaded end portion, belt thread-y ed into said sleeve, and a coinpressiblc wedge supporting element on the outer end of said bolt.

2. An adjusting screw mechanism for threaded sleeve having a flange at one end thereof and being exteriorly Athreaded vat its other end, a lock nut on said exteriorly threaded portion, a bolt screwed into the flanged end of the sleeve, a compressible wedge supporting element on the. outer end of said bolt, a wedge supported bythe coinpressible element, and an indicator on the bolt below the wedge.

l. The combination with a locomotive frame or Ythe like having pedestal legs and a pedestal brace connecting the legs, and a drive box .between the pedestal legs, of a wedge interposed between the drive box and one of the pedestal legs, a sleeve member rotatably mounted in the pedestal brace and passing through the brace, said sleeve being interiorly threaded, a'bolt under the wedge' threaded into the sleeve, and a spring interposed between the bolt and wedge for yieldably `supporting the wedge on the bolt.

5. The combination `with a locomotive frame having a pedestal, a drive box =con' brace and operatively" connected with the bolt. e

'6. The combination with a locomotive frame including a pedestal and pedestal brace with a drive box in the pedestal above the pedestal brace, of a wedge associated with Vthe drive box, said wedge having a transverse slot in the lowervend thereofwhich slot is restricted `toward thejbottom of the' v wedgea bolt having a non-circular head entered into the slot and the wedge, av spring on the top of the belt for urging the wedge upwardly with respect thereto, and an adjusting sleeve vrotatably carried in the pedestal brace to which the bolt is threaded.

7. The combination with a locomotivev frame including a pedestal and pedestal brace with a drive box in the pedestal above the pedestal brace, of a wedge associated with the drive box, said wedge having a transverse 'slot in the lower end thereof which slot is resti'ieted toward the bottom of the wedge, a bolt having a non-circular headentered into the slot and the wedge, a.v

spring on the top of the bolt for urging the wedge upwardly with respect thereto, and an adjusting sleeve rotatably carried in the pedestal brace to which the bolt is threaded,

said sleeve having a. flange at the top thereof adapted to engage theI top of the pedestal brace and having a lock nut at the bottom thereof.

8. The combination with a locomotive frame including a pedestal and pedestal brace with a. drive box in the pedestal above the pedestal brace, oi' a wedge associated with the orive box, said wedge having a transverse slot in the lowei end thereof which slot is restricted tovvard the bottom of the wedge, a bolt having a non-circular head entered into the slot and the wedge, a spring on the top ot the bolt tor urging' the wedge upwardly with respect thereto, an adjusting sleeve rotatably carried in the pedestal brace to which the bolt is threaded, said sleeve having a flange at the top thereof adapted to engage the top of the pedestal brace and having a lock nut at the bottom thereof, and a bracket on the under side of the pedestal bra-ee cooperating with the sleeve and with the nut.

9. The combination with a pedestal of a locomotive 'traine having a pedestal brace thereon and having` a drive box therein, of an adjusting sleeve rotatably mounted in the pedestal brace, a wedge cooperatively associated with the drive boi-z and the pedestal, a bolt threaded into the sleeve and non-ro tatably engaging the head, and a spring interposed between the top ot the bolt and the under 'ace of the .vedge.

l0. rl`he combination with a pedestal ot a locomotive frame having a pedos il brace thereon and having a drive box therein, ol'- an adjusting sleeve rotatably n'iounted in the pedestal brace, a wedge cooperatively associated with the drive box and the pedestal, a bolt threaded into the sleeve and non-rotatably engaging the wedge, a spring interposed between the top ot the bolt and the under ace ot' the wedge, said sleeve having Vits lower end projecting' beyond the bottoni o'if the pedestal brace, and a lock n ut on the projecting end o said sleeve.

ll. rlhe con'ilnnation. with a locomotive frame having a vertically movable drive box therein and a wedge for compensating for wear between the drive box and the trame, of an adjusting means for the wedge including a sleeve rotatably carried in the locomotive frame, a bolt threaded into the sleeve having its upper end slidable and non-rotatably engaging the wedge, and a spring interposed between the bolt and the wedge.

l2. The combination with a pedestal ot a locomotive trame having a pedestal brace thereon and having a drive box therein, of an adjusting sleeve rotatably mounted in the pedestal brace and having a flange at the top thereof in contact with the pedestal brace, said llange and pedestal brace having cooperating locking surfaces which serve to normally hold the sleeve against rotation in the pedestal brace, a wedge cooperatively associated With the drive box and pedestal, a bolt threaded into the sleeve and non-1o tatably engaging the wedge, a spring Vinterposed betwen the top of the bolt and the under surface of the wedge, said sleeve having its lower end projecting beyond the bottom of the pedestal brace, and a lock nnt on the projecting end ot said sleeve.

13. rlhe combination with a locomotive rame or the like having pedestal legs and a pedestal brace connecting the legs, one ot said legs having an inclined inner tace, ot a drive` box inthe pedestal iframe havingY an incline-d` lace opposed to the said inclined lace ot the pedestal leg', the inclination of the two laces being opposite, a wedge having oppositely inclined, faces thereon interposed between the inclined face otthe driving box and the inclined `face of the leg, and means for adjnstably and yieldably supporting the Wedge on the pedestal brace.

In testimony' whereof l have hereunto set my hand.
